Question

The adjacent side of a rectangle are (x - 2y + 3) unit and ( x + 2y) unit . find its area

pls tell me the answer first I mark you as brainliest ​

Answer 1

Explanation:

area of rectangle=l*b

=(x+2y)(x-2y+3)

=x(x-2y+3)+2y(x-2y+3)

=x²-2xy+3x+2xy-4y²+6y

=x²-4y²+3x+6y

Answer 2

Answer:

Given that,

Length (l)= x-2y+3

Breadth (b)= x+2y

Area of rectangle =l×b

= ( x-2y+3) × x +2y

= x²- 4y² + 3 sq.unit
